Technical FAQs

Q1: What is the main function of the Allen-Bradley 1606-XLP50E?

It converts AC or DC input power into regulated 24 V DC power for industrial automation equipment, including PLCs, sensors, relays, and control circuits.

Q2: What input voltage does the 1606-XLP50E support?

It accepts 100–240 V AC input at 47–63 Hz. It also supports 85–375 V DC input, providing flexibility for different power supply systems.

Q3: What are the output voltage and current ratings?

The nominal output is 24 V DC, adjustable within a range of 24–28 V DC. The rated output current is 2.1 A at 24.5 V, with a maximum output power of 50 W.

Q4: Can the output voltage be adjusted?

Yes. The output voltage can be adjusted from 24 to 28 V DC to accommodate compatible equipment requirements.

Q5: Does the 1606-XLP50E support parallel operation?

The standard 1606-XLP50E is not specified for parallel operation. For applications requiring parallel connection or redundancy, consider a model designed for that function, such as the 1606-XLP50EZ.

Q6: What is the typical efficiency of this power supply?

Its typical efficiency is approximately 89%, helping reduce energy losses and heat generation during operation.

Q7: What protection rating does the power supply have?

The unit has an IP20 protection rating. It is intended for installation inside suitable electrical enclosures rather than direct exposure to water or dust.

Q8: What is the operating temperature range?

The specified operating temperature range is -10 to +70 °C. Above +60 °C, output power derating must be considered.

Q9: What should be checked if the 24 V DC output is unavailable?

Check the AC or DC input voltage, input wiring, terminal connections, output load, and possible short circuits. Also verify that the input voltage is within the permitted operating range.

Q10: Can the 1606-XLP50E replace another 24 V DC power supply?

It may replace another power supply when the input voltage, output voltage, rated current, power capacity, mounting arrangement, and terminal connections are compatible. A 50 W rating alone does not guarantee interchangeability.
